changed DatabaseCleaner strategy to truncation in all specs except features (should make the specs run faster). Also cleaned a bit some unused code.
removed unused fixture
fixed specs for unsubscribes (they were broken after the change in DatabaseCleaner strategy)
fixed Unsubscribe class for tests, the notification_type cache variable was mesing up the new transaction cleanup strategy in specs
changed unsubscribe spec back to compare only the notification_type_id and not the name
used block syntax according to our code convetions do...end for multiple lines. tidyed up a bit the before blocks with the current_user stubbing
small refactor of the current_user stubbing
fixed problem with routing filter in specs (disabling of routing filter should be in before(:each)
